Just the first part, the rest requires measuring voltages and resistances with a meter. Some at the ECM connector which may be difficult. (And you'd need to be careful not to fry any electronics in the process.(Disclaimer))
Basically it looks like if the VCDS part checks out and you are getting 5 Volts at the Throttle Control Module they have you check the wiring resistance from the Throttle Control Module to ECM and depending on what pins have certain resistances you'd ether replace the ECM!!!! or the Throttle Control Module.
